Reminds me of one of my first MPC games.
I birdied the first hole (Kaiwah), opponent parred.
2nd I birdied, opponnent parred
3rd he drove thru the Fairway in the heavier stuff, then wanted to drop the match.
I said no.
He then went on to tell me "he'd find me", "I drive a Harley".
I told him to message me when he got to California and we'd go from there.
Really folks, threats, bad language, etc., is just a ruse to take you out of your game.
